It carries a rated continuous current Iu of 32 A at ambient temperatures up to 50 °C — no derating needed in a typical 40 °C panel — and begins derating above 55 °C, reaching 28.8 A at the 70 °C operating maximum. Breaking capacity is 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 690 V. That's enough to interrupt high-fault conditions on most commercial and industrial secondary distribution without cascading upstream — the 415 V figure covers common 400 V class panels. The auxiliary release is ordered separately as 3VA9688-0BL32.
The SENTRON series carries CE, UL, and IEC certifications per Siemens standard practice. RoHS and REACH declarations are available from the manufacturer upon request.
Mount it inside a panel with a door or cover; it is not intended for open washdown areas. The 3-pole footprint is standard for a 32 A MCCB, so it fits existing SENTRON or comparable DIN-rail or screw-mount backplates. A voltage trigger and trip indicator are present on the front, allowing quick visual confirmation of a tripped state during fault isolation — no need to break the seal to check.
